Type of Posting: General Announcement

Posting Date: 01–Jun–2017

USP is aware of an issue with the cross reference links to General Chapter <191> from content within the USP 40–NF 35 online edition and Supplements. Currently the cross reference links direct users to a version of General Chapter <191> that is no longer official. The new version of General Chapter <191> became official on May 1, 2017. The cross reference links will be updated in USP 41­–NF 36 online when the unofficial version is removed from the publication.

Please check the first line under the title of General Chapter <191> Identification Tests—General, containing the specific official date, to ensure you are accessing the intended version of the General Chapter.
